⚙️ chore: Resolve Build Warning, Package Cleanup, Robust Temp Chat Time (#9962)

* ⚙️ chore: Resolve Build Warning and `keyvMongo` types

* 🔄 chore: Update mongodb version to ^6.14.2 in package.json and package-lock.json

* chore: remove @langchain/openai dep

* 🔄 refactor: Change log level from warn to debug for missing endpoint config

* 🔄 refactor: Improve temp chat expiration date calculation in tests and implementation
